Tanning bed bulbs and lamps should be replaced when they have been used to 80 percent of their expected life cycle, and typically hit this mark about one year after they have been installed. Low-pressure lamps have a life cycle of 300 to 1,700 hours, while high-pressure bulbs last 300 to 9,500 hours.
You can use your tanning bed bulbs until about the 500- to 800-hour mark, depending on the manufacturer and type of bulb. At the 500-hour mark, your bulbs may be only running at about 50 percent effectiveness. After about 1000 hours, your bulbs may not be working well at all.
